Said valveha's a pair of spaced ia'andfll near opposite ends thereof which are magnetite selectively register, respectively, with resp water fromc a'pressure source delivered from a pii ie l?" t o an elongated chamber l6, may pass th'rougli the valve to one or the other side of the pistol; Valv G also has ezihaust parts, as at il, near end adapted for registration at times with alihed outlet passages lBand ill in the body D H" are identi c al and each has an upper seated irraslot 2 in -valve G, and a heel portion M a-clarified t obe-engaged by actuator 25 or 25 WhQlflPlSjjQll E i s retracted in direct" llllehhers Hlandlfare enclosed at their 0L be sides by shields-it which may be formed on or In order't'o'effect the reciprocation of piston E I gesjlg and in the cylinder body and also, ectiv'ely, with passages l4 and i5, whereby theldat ilfiand 23, respectively, on 1 r I actuators 25 and 25 fixed in position onflstem l of piston E. Members H and e 3 1 attached to the cylinder heads 2 and 3, as shown in Figs. 1 and 6, so as to prevent the operation of valve G due to a surge of Water in cylinder D cocasioned by reciprocation of the agitators F and F.

The assembled unit shown in Fig. 1 is insertable into tank A and is concentrically supported as by means of one or more brackets 39 fixed to cylinder D or its heads 2 and 3 and to the Wall 3| of tank A, said tank having detachable ends 32 and 33, one of which may be removed for attaching the unit to the tank (Figs. 1 and 3).

As shown in Figs. 1, 7 and 8, we provide detent means near one or both of the members H and H, which, at least as shown, are mounted in the cylinder heads 2 and 3 and are adapted to hold valve G in its position during the movement of piston E against accidental displacement but, more particularly, are so formed and spaced that in the event of the stoppage of the piston, as at closing time, or otherwise, the valve G will be urged to one or the other extreme of movement in order that upon a renewal of operation the piston E will complete its previously intended and partially completed stroke without occasioning a lock-up requiring external or artificial efiort or means. S0, in each of heads 2 and 3 we provide a detent J which is formed with a rounded head 34 slidable in a counterbore 35 and having a stem 36 slidable in a pilot bore 31, with a compression spring 38 confined between the head 34 and the bottom of said counterbore and tending to urge the head into operative engagement with valve G.

Valve G is formed with two angular notches 39 and 46 adapted to be selectively engaged by the heads 34 of the detents J respectively, and

said notches are so arranged that when one detent (Fig. 8) is seated in a other detent will notch 39 or 40 the rest in such a position as to insure a suflicient movement of valve G to seat v the other detent (Fig. '7), or vice versa. Thus, if pressure is released on either side of piston E the valve G will either remain locked in one position or the tension of spring 38 on an oppositely operative detent J will occasion its movement to another position, depending upon the position of the piston at the moment of its stoppage. e

As shown in Fig. 1, piston E is at the extreme of its movement to the right and water from pipe B flows through chamber l6, and passages l5, H and Hi to that portion of cylinder D to the right of the piston, and thereby will move the piston to the left so long as valve G remains in the position shown. During suchperiod water is exhausted from that to the left of the ll, 25.! and !9 to the tank A.

As the piston nears its leftward extreme of movement the actuator 25' engages portion 28 of member H and thus'slides valve G to the right until the inlet passages M, [Band [2 are in registration, and the exhaust passages 18, I 0 and ii! are also registered, whereupon pistonE will begin and continue a movement to theright until actuator 25, through its engagement with portion 23 of member H again moves valve G to a position necessary for a return stroke of the piston.

The agitators F and F are so formed as to produce a maximum agitation of the liquid contents of tank A, there always being provided a substantial space above the level of the liquid so that the liquid may be readily displaced and portion. of the cylinder piston through passages I8,

I at one side of the piston and exhausting liquidbroken up into globules whereby the gas (above the liquid level) has an opportunity to saturate the water.

Our improvements, therefore, provide an automatically operative hydraulic means for charging water with gas by the employment of water pressure from a source of supply as an operating medium, thereby eliminating the necessity for electric motors or other mechanical media, and without impairing the volume of production of charged water 01' the degree of saturation thereof.
